Infiniti Prototype 10 single-seat speedster unveiled at Pebble Beach

PEBBLE BEACH, Calif. — Infiniti's new Prototype 10 takes inspiration from last year's Prototype 9 concept, but instead of minimal bodywork and open wheels, adopts the long and sinuous profile of classic speedsters of the past. And the concept's electric powertrain hints at the Japanese automaker's future. Infiniti says that all new production models from 2021 onward will have some sort of electrification, spread across pure battery-electric vehicles, parallel hybrids and e-POWER series hybrid powertrains. The overall shape of the Infiniti Prototype 10 recalls classic race cars like the 1950s-era Jaguar C- and D-Types. There's virtually zero wind protection for the single passenger, but there's a prominent headrest that incorporates a fin-shaped aero element. Air intakes are plentiful and festooned with close-set vertical bars that remind us of last year's Prototype 9 concept. There are lots of striking details in the Prototype 10's flowing bodywork. Slim, almost slit-like lights up front sit below the level of an Infiniti logo highlighted by negative space. In profile, a virtual line cuts across the vehicle front to rear. We look forward to seeing how some of these elements are incorporated into future production vehicles from Infiniti.

But we do know that the concept uses Infiniti's steer-by-wire Direct Adaptive Steering system. We can also see that the interior compartment is minimalist in design, clearly in an effort to keep the driver's focus firmly on the road ahead. Though much of the commentary surrounding the Prototype 10 will undoubtedly be about its radical bodywork, it may be the vehicle's chassis that is most relevant to Infiniti's production electric vehicle plans. The company describes the Prototype 10's chassis as rigid, modular and flexible with a flat floor and says such a platform would underpin its future electrified vehicles, including sedans, SUVs and sportscars. Stay tuned for more on the Infiniti Prototype 10 as we meander the remainder of Monterey Car Week here in California. Related Video: This content is hosted by a third party.

Nissan Rogue, Pathfinder and Infiniti QX60 recalled for loose lug nuts

Nissan has announced a small recall affecting 334 vehicles built just a few months back. 2014 Nissan Rogue and Pathfinder and 2014 Infiniti QX60 CUVs built between March 7 and March 10, 2014 could be susceptible to a loose lug nut on the passenger side wheels.
We shouldn't have to explain why a loose lug is a bit of an issue. Thankfully, it's also a ridiculously easy fix. Nissan obviously recommends reporting to your local dealer - and it will begin notifying owners of affected vehicles - but this is one of those rare recalls that has an easy DIY element to it.
Take a look below for a brief bulletin from the National Highway Traffic Safety Administration.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
